SHADE- To all whom it may concern:

Be it known that I, Gnoncr. A. G-aU'rHmR, States, residing at Hartford, in the county of l'l artford and State of Connecticut, ha re invented a new and useful Improwrment in Shade-Holders, of which the following is a s wciiication.

This invention. relates to a' stitucture which is particularly adapted for uhe .iii' trolley and other electric railway can in which there is considerable \"lbltllZlO'll illltl jar, for holding the shades that are employed to cover and diffuse the light froln the lamps, although, of course, the structure is equally serviceable for holding lamp shades in other places.

In electric cars, whether they run on highways or private roadbeds, the lamps and shadesare subjected to hard service owing to the vibration and jar incideiltto the motion of the cars and to the fact that it necessary to frequently clean the shades and the lamps, which labor is usually performed by unskilled and possibly careless employees.

The object ol this invention is to provide a simple, neat and strong holder which can be very easily manipulated for securely fastening the shade in service position or releasing the shade so that it may be taken down for cleaning, and which cannot be left after the shade has been put up unless the holder is positively secured in such manner that the shade cannot possibly drop down and become broken or cause injuryto any person happening to be beneath. In at taining this end the base end of theshade is positively clamped between a strong and substantial part that extends within it and a part that is securely fastened thereon and extends over the outside of the end of the shade. The part that eXtendswithin the shade is provided with means which are designed to firmly engage with a part that projects from the supporting-base, which means are positively held againstdisengage ment by a sliding part that is arranged in such manner that it cannot be operated to lock the connecting means against disen-- CONNECTICUT, A CORPORATION OF CON- HOLDER.

member. Fig. 3 is a central vertical section I of the holder and the upper end of a shade with the parts locked together as in. use. Fig. 4 is a section'of one side of the lower part of the hub ofthe base member and the upper part of the sleeve of the shade memer. Fig. 5 is a side view of the hub of the base member. Fig.6 is a plan of the shade member.

The drawings show the ordinary type of lamp connections 1 attached in the usual manner to a common form'of porcelain base 2. The base member of the metallic shell 3 of suitable design to cover the base, with a downwardly projecting hub also to properly locate the when it is applied to the base holder has I a lips may be formed act to prevent the collar from dropping I its upper end projects some distance beyond.

On the lower endof the sleeve and between it and the inner wallfof the shade it is desirable to place a packing ring 10 of some soft material for the purpose of cushioning the,

engagement. In slots in the sleeve are a number of'spring arms 11, the upper ends of which are bent inward and are designed to enter the slots in the hub of the base member of the holder when the parts are assem bled for use. Screwed on the exterior ofthe' shade sleeve is a cap 12 which is designed to be turned down against the end of the shade so as to securely fasten together the shade and the shade member. A packing ring 13 may be placed in this cap so as to bear against the edge of the shade for cushioning the parts.

thrust up through the shade and the cap is screwed on the sleeve untiLtheedge of the shade is firmly clamped between the sleeve and cap. The shell with its hub is fastened over the base and the lamp connections. To nut up the shade the sleeve which supports In assembling the members the sleeve is i it is thrust upwardly onto the hub of the base, which it closely fits, until the inturned ends of the spring arms on the sleeve are opposite the slots in the hub. Then when the collar on the hub is drawn down the ends of the arms are forced into the slots. As long as this collar is down, and it cannot be drawn down until the ends of the spring arms have entered the slots,,the ends of the was cannot work out of the slots and allow the shade to drop. In order to remove the shade the collar on the hub of the base member is pushed up. This releases the spring arms so that the shade will drop free and may be removed for cleaning. A small annular groove 14 is made in the inner wall of the collar so that the ends of the spring arms, which have a slight outward bend as Well as an inward bend, will enter this groove and prevent the collar from accidentally moving upward and releasing the arms so that they can disengage from the slots in" the hub. The sleeve which holds the shade cannot be pushed up on the hub until the lips on the hub enter the slots in the sleeve whichcontain the spring arms and the parts are in proper relative pos1- tions for the spring arms to engage the slots in the hub, and the collar which locks the spring arms cannot be drawn down without forcing the ends of the arms into the slots. Thus while the shade can be easily and quickly removed by proper manipulation it cannot accidentally drop after it has been once put up. If it is improperly put up it will drop before the attendant leaves as there is nothing to hold it until the locking sleeve is drawn down which, as

- stated, cannot be done until the parts are in proper positions to be locked.

With this construction the shade cannot drop off as a result of any chipping or iceable for electric car service.

breaking of the rim around its base, and it cannot be left until it is positively locked in a safe position and it cannot become unlocked by any vibration, shaking or shock to the parts. For this reason the holder, as previously pointed out, is particularly serv- The holder may be made for all sizes of shades although it is especially serviceable for shades which are large and heavy.

The invention claimed is: I

1. A shade holder comprising a supporting member, a shade holding member independent of but having its fupper end fitting and adapted to b'e-slid longitudinally upon the supporting member, fingers on the shade member normally out of engagement with but adap'ted to be engagedevith parts of the supporting member, and a collar adapted to he slid longitudinally onto the shade memgaged with walls of the slots in said hub,

and a collar fitting and sliding longitudinally on'the hub and the upper part of the shade member into contact with the fingers and force the ends of thefingers into the slots in the hub.

3. A holder having'a base member with a slotted hub, a shade memberv adapted to fitsaid hub, means for securing a shade to said shade member, spring arms carried by the shade member and adapted to engage the slots in the hub of the base member, and a collar sliding on the hub of the base member and adapted to hold the spring arms in the slots in the hub of the base member and said collar having means whereby it is held by member with a hub projecting therefrom, a

shade member fitting said hub and having means for engaging the inside of a shade, a cap screwed on the shade member and cooperating with said means thereon for se curing ashade thereto, fingers on the shade member normally out of engagement with but adapted to be forced into engagement with the supporting member, and a collar fitting said members and adapted to slide longitudinally thereon into contact with the fingers and force them out of normal position and into engagement with the supporting member so as to lock the members together. I

A shade holder having a base member with a hub projecting therefrom, a shade member fitting said hub and having means for engaging the insideof a shade, a cap screwed on the shade member and cotiperating with said means thereon for securing a shade thereto, spring fingers to connect the members, said fingers being normally out of engaging position, and acollar fitting said members and adapted to slide longitudinally thereon into contact with the fingers and force them out of normal posi tion and into engaging position so asto lock the members together.
